Goswami, who left Sky suddenly after heckling Greg Dyke at an RTS dinner last year, has joined forces with former ITV director of channels Chris Griffin, who left his job three months ago.
Chris Goodall of Enders Analysis is also believed to be involved, along with a number of other undisclosed names.
Still in the early days of the venture, Aggregator TV hope to compete with pay TV by aggregating content and broadcasting it via the broadband DSL network. A major undisclosed financial investment company is backing the venture.
BT is planning to launch its TV over broadband service early next year and has teamed up with Microsoft, while the BBC is also trialling Interactive Media Player (iMP) in the corporation's first foray in to broadband TV.
The iMP is based on peer-to-peer technology, and lets people download programmes the BBC owns the rights to for up to seven days after broadcast.
BSkyB is also making its own set-top boxes broadband-enabled.
